Applicationlei September 9,1907: v Serial No. 391,889. i Op To all whom. tt may concern:

Be it known that I, HERBERT L. SMiTH, of Clinton, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Crimping Apparatus for Electric Welding Machines, of which the following is a specification.

OIhis invention relates to a new and improved crimping apparatus for electric welding machines for welding wire fabrics.

Figure l in side elevation shows a construction made in accordance with my invention, a part of the center of the girth being broken away. F ig. 2 is a cross-sectional ,view taken on line 2 2 of Fig. 1, looking in' the direction of the arrow. Fig. 3 is a cross-sectional view on line 3-3 of Fig. 2.

The same letters of reference indicate the same parts in all of the figures.

In machines of this general class it is frequently found desirable to crimp the strand jwire; in other words, to form bends in said wire, either for purposes of ornamentation or for purposes of aitility, in order to provide a yielding capacity in the fabric. In the use of such crimping devices, it isnecessary to have the crimping-j aws accurately located in o rder to crimp the strand wires between the stay wires at the proper. point. The stay wires are' applied to the strand wires at different distances in different classes of goods, so that some provision is necessary to readily and accurately change the crimping-j aws to correspond with any selected position for the stay wires. 'By my invention, the above described result is secured by an efiicient and simple mechanism.

1, 1, represent parts of side members o f the frame of a machine for electrically welding wire fabric, such as for instance, is shown in Ilnited States patent to Perry, No. $13,823, granted February 27, 1906.'

My invention relatesonly to one detail of that machine, and the main part of the machin(` need not, therefore, be described.

I represents a gi1tl1,cach end of which is formed with Allanges 4, 4, which extend out beyond each side of the girth. In each -iiange 4 is formed a slot 5.- A bolt 6 is arranged in each slot 5, the head of the bolt engaging the iange 4, the end of the bolt being tapped into the girth. By this means each end of the girth is connected with the frame 1, by means of the slots 5 and bolts 6, which permits the ends vof the girth to be adjusted up and down by means hereinafterdescribed, and thereafter locked in adjusted 'position by tightening the bolts 6.

7- represents a screw-threaded` hub formed in the flange 4 on each end of 4the girth. In each screw-threaded hub is arranged a complemental screw-threaded rod-`8. The upper end of each rod is arranged in a hub 9 of the framework and secured in position by a nut 10.

girth.

12 represents 'a hand wheel secured t6 the lower end of each rod 8 below the hub 11, it being understood that the rod 8 is not provided with screw-threads at the point where The lower end of eachrod extends j through a complemental hub 11 below the it engages the hubs 9 and 11, but is free to turn therein. By locsening the bolts 6 and turning the hand wheels 12 the ends of the girth may be adjusted up or down, in order to bring the crimping members in the right poe sition with respect to thev fabric being made. Thereafter, the bolts 6 are tightened, thus rigidly securing the ends of the girth to the framework 1, and relieving the Screw-threads of the bolts 81, from strain.

Upon the girth as Shown, there are arranged a series of stationary crimping jaws 1.4, a series of movable crimping jaws 15 carried by the slide 16, the said slide being operated by a cam 18, as set out in the before-mentioned patent to Perry, No. 813,823.

Having thus explained the nature of my inyention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, what I claim and desire to secure by Letters Patent is In a machine for making welded wire fab ne o nized witha. suitable framework,V a 'desired' point and thereafter locked nposi- 10 gir -ormed'upon each end with a flange, a tion by seid bolts. y
